The video deposition of Gates was pretty damning during their anti-trust case. I just remember watching it and having my image of Gates shattered right in front of me. The amount of unhinged arrogance and hubris he had was startling. I know it really damaged his clean cut, good guy image and many of my friends said it completely reversed their opinion of him.
(I see the full 11 hour deposition is also on YouTube, but I think I'll save that for another day.)
So far, being 10 minutes in, I see a little bit of what you mean, but I haven't gotten to anything "unhinged" yet. He just seems like a bit of a smug nerd who's clearly enjoying going toe-to-toe with one of the country's top lawyers.
Do you remember anything that jumped out for you from the deposition? I'd love to see more of what you're getting at.
